Sol Strike

You've honed your martial skills and trained your body to withstand tremendous pain and fatigue. As part of your training, you have learned how to draw on your inner strength and unleash it in a powerful burst attack.

While you are not exhausted, you may take a ready action on your turn to focus your energy. If you do not lose concentration on this focus before your next attack action, your next attack is made with advantage and will deal an additional 12d8 + 27 force damage if it hits. After the attack hits, you gain one level of exhaustion.
